What documents do U.S. buyers typically ask for before paying a hair care deposit (COA, SDS, stability, micro)?

Quick Answer (for busy buyers)

Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.

• In the U.S. market, brand owners/Amazon sellers typically want a deposit-ready document pack that reduces compliance and quality risk.
• Common requests include: SDS (for the finished formula and/or key raw materials), COA (raw material COA and/or pilot/batch COA), stability evidence (accelerated/real-time plan and available results), and microbiology results (micro limits/preservation challenge where applicable).
• Buyers also often ask for basic company/product paperwork such as business certificates, product spec, and an information barcode for inventory workflows.
• Operationally, we usually align this with your development steps: confirm the formula concept, make and confirm samples, then arrange send-out testing and track the inspection report through our partnered testing channel.
• We can also support overall brand materials (product positioning, structure, instructions, price list) and full packaging/VI coordination.
• Planning notes: MOQ is generally 1000-3000 units (e.g., simpler items can start at 1000; complex skincare sets/packaging/formula often 3000).
• Bulk production is typically 10-20 working days after final confirmation; packaging ordering often takes 10-30 working days (e.g., glass bottle ~15 days, acrylic bottle ~30 days).
